The invention relates to a test bench for testing wind turbine equipment. The test bench comprises one or more load applying means directly and/or indirectly applying load to the equipment, drive means of the test bench for rotating an input shaft of the equipment at least during a part of the test, and simulating means for establishing wind turbine like conditions or facilities. The invention further relates to a method for testing wind turbine equipment. The method comprises the steps of positioning the equipment in, on or at a test bench, rotating an input shaft of the equipment by drive means of the test bench, and directly and/or indirectly applying load to the equipment by means of load applying means of the test bench.
